SPECIFICATION forming part of Letters Patent No. 672,654, dated April23, 1901.

Application filed July 2, 1900. Serial No. 22,255. (No model.)

To all whom it may concern.- Be it known that We,'ELLIE N.SPERRY, WIL-LIS F. HOBBS, and NELSON B. KEYES, citizens of the United States,residing at Bridgeport, county of Fairfield, State of Connecticut, haveinvented new and useful Pliers, of which the following is aspecification.

Our invention relates to the manufacture of sheet-metal pliers,ticket-punches, &c., and has for its object to provide tools of thischaracter which may be formed from relatively light sheet metal whichshall be so constructed as to give the maximum strength where it is mostrequired-2'. e., at the pivotal pointand whose construction shall besuch as to inherently providea spring action against both heads of thepivot, so that the latter will be held tight at all times and the Wearof use be compensated for, these results, moreover, being accomplishedwithout thickening the pliers to the slightest extent at the pivotalpoint. With these ends in view we have devised the novel sheet-metaltool, of which the following description, in connection with theaccompanying drawings, is a specification, reference characters beingused to designate the several parts.

Figure 1 is an elevation of our novel pliers; Fig. 2, a back viewthereof; Fig. 3, a plan 0 view of one of the blanks from which themembers are formed; Fig. 4, a transverse section on the line 4 4 in Fig.1; and Fig. 5 is a view similar to Fig. 1, illustrating the applicationof ourinvention to asheet-metal ticket-punch.

A denotes the members which are made of sheet metal, and B the pivot.

10 denotes the shanks of the members, and 11 the jaws, both of which maybe of any ordinary or preferred construction, the shape or design ofboth shanks and jaws not being of the essence of our invention.

12 denotes a depression in the. inner face of each member at andextending both sides of the pivotal point, the corresponding outer 5face of the member, however, being perfectly straight, as shown in thedrawings. 'Ihis de- It will be noted (see Fig. 4) that at the pivotalpoint the members are of anar- I'OW U shape in cross-section. We arethus enabled to utilize the full strength of the four plies of metal,(washers, not shown, may or may not be used, as preferred,) and wefurther utilize to the fullest extent the spring action of the membersagainst the heads 13 of the pivot, whereby the latter is heldtight atall times to compensate for the wear of use.

Having thus described our invention, we claim- 1. Sheet-metal plierswhose members are made narrowly U-shaped in cross-section at the pivotalpoint,each member being provided with a depression which receives thecorresponding portion of the other member, so that the full strength ofthe metal of both members and also the spring action thereof against thepivot are utilized.

2. A hand-tool comprising two members crossing each other and pivotedtogether, each of said members being completely U- shaped incross-section at the pivotal point, the pivot passing through fourthicknesses of metal, the said four thicknesses being strengthened andpossessing a spring action due to the curved or bent portions of themetal which connect the four thicknesses in two pairs.

3. A hand-tool comprising two members crossing each other and pivotedtogether, each of said members being completely U- shaped incross-section at the pivotal point, the handle and jaw portions of thetool being substantially equal in width and the middle portion of eachmember being formed witha recess or depression on its inner sidesurrounding the pivot-point, the pivot passing through four thicknessesof metal, the said four thicknesses being strengthened and possessing aspring action due to the curved or bent portion of the metal whichconnects the four thicknesses in two pairs.

In testimony whereof we affix our signatures in presence of twowitnesses.
